GEORGE SPENCER FRARY, OF CLEVELAND, OHIO.

ATTACHMENT FOR SLED-RUNNERS.

SPECIFICATION forming part of Letters Patent No. 765,966, dated July 26,1904.

Application filed March 28, 1904:. Serial No. 200,250. (No model.)

To all whom, it may concern:

Be it known that 1., GEORGE SPENCER FRARY, a citizen of the UnitedStates, and a resident of Cleveland, county of Cuyahoga, and State ofOhio, have invented a new and useful Improvement in Attachments forSled-Runners, of which the following is a specification, the principleof the invention being herein explained and the best mode in which Ihave contemplated applying that principle, so as to distinguish it fromother inventions.

My invention relates to attachments for sled-runners, and has for itsobject the provision of shoes for such runners that may be preventedfrom slipping off or being bent or broken off the runners, that can beattached to the latter without the necessity of bolts, screws, or otherrigid fastenings that would weaken the runner, and that shall allow theshoes to spring up and down freely, according to the pressure exertedupon the sled.

Said invention consists of means hereinafter fully described, andspecifically set forth in the claims.

The annexed drawings and the following description set forth in detailcertain means embodying the invention, such disclosed means constitutingbut one of various mechanical forms in which the principle of theinvention may be used.

In said annexed drawings, Figure 1 represents a side view of asled-runner with my invention applied thereto, also a slightly-modifiedform of said invention. Fig. 2 represents a vertical sectional view ofsaid modification, taken upon the plane indicated by the line 2 2,Fig. 1. Fig. 3 represents a side view of a sled-runner with a secondmodified form of my invention applied thereto; and Fig. 4 represents avertical sectional View taken upon the plane indicated by the line 4:4:, Fig. 3.

Any ordinary form of runner for a sled, sleigh, sledge, or otherconveyance designed to slide upon runners provided with shoes may beprovided with my improved attachment, and one such is illustrated at Ain the drawings. A suitable shoe B is provided for such runner and isattached to the same at the front and rear parts only of said runner byscrews Z) Z) or in any other desired manner. The runner A is providedwith a vertical elongated slot or opening a in its lower edge, and intothis opening projects a small lug or pin Z), attached to the shoe B, andwhich is of substantially the same height as the depth of said opening.Said pin 6 registers loosely within the opening a and is adapted toslide up and down within the same as the shoe is sprung by the differentpressures exerted upon the sled. The second opening a of the runner A inFig. 1 is provided with a metallic collar (0 covering the periphery ofsuch opening and lying flush with the under side of the runner for ashort distance on either side of the opening, the latter being of adiameter suflicient to accommodate such collar and still permit theloose registration of the pin 6 within the same.

In the second modification (illustrated in Figs. 3 and 4) the collar isextended fully across the under edge of the runner flush with the same,extends longitudinally along said edge for a considerable distance inboth directions from the opening, and is carried upwardly upon bothsides of the runner to substantially the same height as the slot (0,thus providing a sheathing a completely enveloping that part of therunner into which the pin 6 projects and being provided with an openingin its under side through which the pin passes. Such sheathing isfastened to the runner A by transverse bolts 0* or in any other suitablemanner.

It will be noted from a study of the abovedescribed mechanism that theopenings (0 a and the registering pins 6 b afford means for securelyholding the shoe to the runner, so that the shoe cannot spring off thelatter or be bent or broken oif from the same, that the free verticalplay of the pin Within the opening provides for the spring of the shoedue to the different pressures exerted at different times upon the sled,that the runner and shoe are thus securely fastened together without theuse of vertically-located screws, bolts, or other rigid fastenings thatwould tend to split or impair the strength of the runner, and that theyare relatively movable without impairing the efficiency of suchfastening. Pins 5 and openings (4 may be of any number, the

runner illustrated in the drawings being provided with two.

The modifications illustrated provide the same advantages as the simpleform of the invention, but tend to protect the runner from wear somewhatmore effectively. In the form illustrated in Fig. 2 the inner peripheralcollar (0 protects the wall of the opening a from wear due to the upwardand downward movement of the pin 7), and in the form illustrated inFigs. 0 and 4 this strengthening feature is extended still further byproviding the sheathing (1- as shown, which protects the runner bothfrom the pin 7/ and from the contiguous portions 7/ of the shoe B andalso from the lateral strain to which the runner is often subjected.This strain upon the runner, which is often very severe and is apt tocrack or break the same, is obviated to a great extent by providing thesheathing a", as shown. Such advantages and additional features,however, are not necessarily included in an embodiment of my invention,which consists in its simple form of the elongated openings in therunner and the registering pins upon the shoe, as shown and described,with the consequent advantages stated.

Other modes of applying the principle of my invention may be employedinstead of the one explained, change being made as regards the meansherein disclosed,provided the means stated by any one of the followingclaims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as myinvention 1. The combination with a sled-runner provided with anopening, of a shoe for said runner provided with means constructed toplay in said opening concurrently with the spring of the shoe.

2. The combination with a sled-runner and a shoe therefor, of anelongated opening in the lower edge of said runner. and means attachedto said shoe and adapted to play in said opening as said shoe springs upand down.

3. The combination with a sled-runner and a shoe therefor, of anelongated opening in the lower edge of said runner, and a pin attachedto said shoe, adapted to enter said opening to retain said shoe in itsproper position upon said runner, and constructed to travel up and downin said opening concurrently with the spring of the shoe.

4. The combination of a sled-runner, a shoe therefor secured to the sameat the extremities only of said runner, slots in the under edge of saidrunner, and pins attached to said shoe, registering with said slots, andconstructed to play in the latter as the shoe springs up and down.

5. The combination with a sled-runner and a shoe therefor, of a verticalelongated opening in the lower edge of said runner, a collar boundingthe periphery of said opening, and a pin attached to said shoe and.adapted to continuously travel up and down in said opening a distancedependent upon the pressure exerted upon the sled.

6. The combination with a sled-runner and a shoe therefor, of a verticalelongated opening in the lower edge of said runner, a me tallicsheathing bounding said runner adjacent to said opening and extending upinto the latter to cover the periphery thereof, and a pin attached tosaid shoe and adapted to enter said opening a distance dependent uponthe weight borne by the sled.

7. The combination of a sled-runner, a shoe therefor secured to the sameat the extremities only of said runner, elongated openings in the underedge of said runner, pins attached to said shoe and adapted to registerwith said openings to retain said shoe in its proper position upon saidrunner, and metallic collars located intermediately of said pins and thewalls of said openings, said pins adapted to continuously travel up anddown in said openings at distance dependent upon the pressure exertedupon the sled.

Signed by me this 2+Lth day of March, 1904.
